You've all read my simple illustration of the pencil and flatland, so I won't bore with it now. But the restrictions act as a protection and a blessing purveyor, since we may exercise faith where we have no tangible proof, thus we may exercise faith using our spiritual eyes and ears. we do it when we read the Bible. We do it when we give thanks to Him for His Grace. We spiritually have the substance of things hoped for (spiritual purity, through Him) as the evidence of things not seen (beyond the 3S1T realm of our senses where we remain sinners aved by His Grace).
